Bug 101993 – proftpd build results in unresolved symbol 'setproctitle'

• Product: Gentoo Linux
• Status: RESOLVED WORKSFORME

[Description Harald Welte 2005-08-10 08:33:49 UTC]

When building net-ftp/proftpd-1.2.10-r7 on ppc64, the configure script shows: 
 
checking for setproctitle... no 
checking libutil.h usability... no 
checking libutil.h presence... no 
checking for libutil.h... no 
checking for setproctitle in -lutil... yes 
 
However /usr/lib/libutil doesn't provide a 'setproctitle' symbol.  So the resulting proftpd 
doesn't run: 
root@vishnu log # proftpd  
proftpd: symbol lookup error: proftpd: undefined symbol: setproctitle 
 
I've looked into proftpd's configure.in script, but I couldn't find something wrong... 
 

Reproducible: Always
Steps to Reproduce:
emerge proftpd 
 
Actual Results:  
proftpd with unresolved symbol "setproctitle" 

Expected Results:  
proftpd with no unresolved symbols

This may be related to bug #101470.

As it turns out, it's a linker bug.

A simple program such as 

---
char setproctitle();
int main { setproctitle(); }
---
links just fine. The linker (gcc/ld) does NOT report the unknown symbol at
linking time.  Only at run time there is an error message.

I've already tried -Wl,--no-undefined and -Wl,--no-allow-shlib-undefined - but
it doesn't help.

This is with gcc-3.4.4

Using the following profile:

/usr/portage/profiles/default-linux/ppc/2005.1/ppc64/64bit-userland/power5/

I cannot seem to replicate this problem.  Can others pipe in and test?

My emerge --info is as follows:

emerge --info

This does not seem to be a issue with proftpd but ppc64 related.

[Comment 4 Markus Rothe (RETIRED) 2006-02-01 10:34:57 UTC]

I cannot reproduce this, either. still an issue?

[Comment 5 Tom Gall (RETIRED) 2006-03-05 20:54:01 UTC]

I would recommend looking very closely at a couple of things.

Where is setproctitle supposed to come from?  Some other library outside of proftpd?  If so  objdump -D <thatlibrary>  > /tmp/thatlibrary.txt

Open up the text file, and I'd be willing to be a whole dollar that the symbol you find is actually .setproctitle, which of course is the old style dot naming convention which thankfully is quite dead. So what do you do?  Re-emerge the library the symbol is in, emerge proftpd and like will be happy.
